Causes of Ascariasis in Children

Ascariasis is very common, and there are many causes of this disease. When treating ascariasis, we must proceed according to the cause of the patient's disease, so that the treatment of ascariasis can achieve good results. What are the causes of ascariasis in children? There are many causes of ascariasis in children. During treatment, it is necessary to conduct various physical examinations on the child. A good grasp of ascariasis in children can be achieved, which is conducive to the treatment of the disease.

Causes of ascariasis in children:

Ascaris is the largest nematode that parasitizes the human intestine. It is dioecious and shaped like an earthworm. Live worms are slightly pink or yellowish in color. Adult worms parasitize in the human small intestine and feed on intestinal contents. Female worms can lay up to 200,000 eggs a day. The roundworm eggs excreted in feces become infectious after 5 to 10 days of development and maturity under suitable environmental conditions.

After the eggs are swallowed, the larvae break out, penetrate the intestinal wall, circulate through the portal vein system, migrate to the liver, enter the alveolar cavity through the right heart, go along the bronchi and trachea to the pharynx, are swallowed again into the small intestine, and gradually develop into adults. During the migration process, the larvae can also reach other organs through the blood flow. They generally do not develop into adults, but can cause organ damage. Adult worms have the habit of migrating to other places and drilling holes, which can cause biliary ascariasis and ascariasis intestinal obstruction. Once they block the trachea or bronchi, they can cause suffocation and death. They can also drill into the appendix or pancreatic duct and cause inflammation. It takes 60 to 75 days from human infection to female worm laying eggs, and the life span of female worms is 1 to 2 years.

Patients with ascariasis are the main source of infection. Because female worms lay a huge number of eggs and the eggs are highly resistant to external physical and chemical factors, the eggs can survive in the soil for several months and can survive for 2 years at 5℃ to 10℃ and still be infectious. The main route of transmission is swallowing infectious worm eggs contaminated by food or hands through the mouth. The worm eggs can also be inhaled and swallowed with flying dust.

Human ascariasis is the most widespread human helminthiasis in the world. According to WHO estimates, there are 1.3 billion patients worldwide, and the infection rate is high among children, especially preschool children. About 531 million people are infected in my country, with an average infection rate of 46.99% and a maximum rate of 71.12%. Due to the implementation of a comprehensive enteric infection prevention and treatment program in schools across the country, the infection rate has gradually declined in recent years.

After understanding the cause of ascariasis in children, when treating ascariasis in children, it is necessary to note that the treatment time is relatively long. During the treatment, it is best for children to eat some vegetables and fruits, and reduce the choice of meat to avoid making ascariasis more serious. Parents should also pay attention to this.
